New method to functionalise glass fibers

17 April 2019:

One of the biggest challenges associated with exposed core glass optical fiber-based sensing is the availability of techniques that can be used to generate reproducible, homogeneous and stable surface coating. CNBP scientists report a one step, solvent free method for surface functionalization of exposed core glass optical fiber that allows for the binding of fluorophore-of-choice for metal ion sensing.

Lead author of the paper, published in the journal ‘Sensors’, is CNBP researcher Dr Akash Bachhuka based at the University of Adelaide.

Abstract:

One of the biggest challenges associated with exposed core glass optical fiber-based sensing is the availability of techniques that can be used to generate reproducible, homogeneous and stable surface coating. We report a one step, solvent free method for surface functionalization of exposed core glass optical fiber that allows achieving binding of fluorophore of choice for metal ion sensing. The plasma polymerization-based method yielded a homogeneous, reproducible and stable coating, enabling high sensitivity aluminium ion sensing. The sensing platform reported in this manuscript is versatile and can be used to bind different sensing molecules opening new avenues for optical fiber-based sensing.

Welcome Akash Bachhuka

OLYMPUS DIGITAL CAMERA2 September 2016:

CNBP would like to welcome Akash Bachhuka, Research Fellow, to the Centre for Nanoscale BioPhotonics for a six-month period.

Akash who has just finished his PhD a few months ago at the University of South Australia, will join CNBP Investigator Prof Heike Ebendorff-Heidepriem’s team at the University of Adelaide.

During his time with CNBP, Akash will work with Centre researchers Roman Kostecki and Sabrina Heng on surface functionalisation.

Welcome aboard Akash!
